Well, there is a quick hack you can use that might work for you.  However, 
you get no guarantee of a well formed document since the markup will pass 
through un-parsed.  Anyway, here's the hack if you want to try it....

         Node msgPlaceHolder = page.getElementMessage();
         Node report = page.createCDATASection(sb.toString());
         msgPlaceHolder.getParentNode().replaceChild(report, msgPlaceHolder);

You'll have to make sure that you remove any <html>, <head>, or <body> tags 
from the string of HTML.

The alternative is to load your database-stored HTML document as a DOM.  In 
order to do this, you'll have to parse it with an HTML parser such as 
JTidy, NeckoHTML, or Jivan (which uses NeckoHTML).  You could use XMLC's 
dynamic loading for this purpose, although I believe it expects the data to 
be loaded from a file located in a configured resource path.  I wonder if 
an enhancement wouldn't be to be able to also allow loading from an 
InputStream?  Anyway, I guess I'd try out the CDATA hack to see if that 
works first since it is so simple.
